Abstract
A battery module includes a battery cell assembly including a plurality of battery cells stacked on each other, a base plate configured to support a lower side of the battery cell assembly, a cover plate spaced apart from the base plate and configured to cover an upper side of the battery cell assembly, and an elastic bead unit disposed between the cover plate and the battery cell assembly.
Claims10
A battery module, comprising:
- a battery cell assembly including a plurality of battery cells stacked on each other;
- a base plate configured to support a lower side of the battery cell assembly;
- a cover plate spaced apart from the base plate and configured to cover an upper side of the battery cell assembly;
- and
- an elastic bead unit disposed between the cover plate and the battery cell assembly,
- wherein the battery cell assembly includes exactly one compression pad, the exactly one compression pad being disposed between one battery cell and an adjacent battery cell of the plurality of battery cells, the exactly one compression pad being a unitary member directly contacting the one battery cell and the adjacent battery cell,
- wherein the elastic bead unit includes:
- a contact plate disposed in contact with the battery cell assembly;
- and
- an elastic deformation unit disposed between the contact plate and the cover plate,
- wherein the elastic deformation unit includes:
- a first elastic member disposed at least partially in contact with the contact plate;
- and
- a second elastic member disposed at least partially in contact with the first elastic member and disposed at least partially in contact with the cover plate, and
- wherein each of the first elastic member and the second elastic member is provided with a concave-convex shape such that convex portions and concave portions are alternately arranged and opposing ends of the first elastic member and the second elastic member are spaced apart such that one of the opposing ends contacts the contact plate and another of the opposing ends contacts the cover plate.
